BUTTONHOLE-MARKING MACHINE.

Specification of Letters Patent.

Patented June 18, 1912.

Application filed July 1, 1911. Serial No. 636,461.

spectively, Columbus, in the county of Franklin and State of Ohio, :have invented ccrtaln new and useful Improvements in Buttonhole-Marking Machines, of which the following is a specification.

The present invention relates to improve ments in marking machines and is designed especially for the ,purpose of perfectingthe machine illustrated in application for Patent No. 607 ,5416, filed in the U. S. Patent Oflice February 9, 19 11.

In the above mentioned application a pattern plate having marking punches is used, and devices are employed for the par pose of making indentations by means of said punches, directly upon the work. In the present application a similar pattern plate and marking points or punches are employed, but additional features, such as a work carrier or feeder, and a ribbon are used by means of which the work is marked by inked points instead of being pricked by the punches of the pattern plate. In this instancethe work mentioned are buttonflies for shoes, and by the utilization of the present devices, we are enabled to mark a ,pair of flies at a single operation, thus producing two marked pieces, as a right and a left, for the one pair of shoes.

The invention consists in certain novel features of construction and combinations and arrangements of parts as are. fully illustrated in the drawings and particularly pointed out in the appended claims.

In the accompanying drawings we have illustrated one exampleof the physical em bodiment of our invention constructed according to the best mode we have so far devised for the practical application of the principles.

Figure 1 is a front elevation of a machine embodying the novel features of the invention, Fig. 2 is a plan viewof a portion of Fig. 1. Fig. 3 is a transverse sectional view of Fig. 1 looking towardthe left, showing the carrier or work carriage in position .for

the work to be stamped or printed. Fig. ft

showing the ink ribbon roller and its act-uating device. Fig. 6 illustrates the roller shown in Fig. 5, the ribbon in section, but Fig. 7 is an exaggerated view illustrating the position of the ink ribbon at the time of stamping the work.

For an intelligent understanding of the iresent invention reference should be had to the above mentioned application for.

patent, although a complete exemplification of the essential parts of the invention are illustrated herein.

Between the two standards 1, 1, is supportedthe rotatable drum 2 which is formed ment of the pattern plates 1. Each of these mg pins or marking points 5, and thedrum is rotatable so that a selected pattern may be presented at the upper side of the drum.

A driving shaft, suitably rotated is inclicated at 6, .journaled in bearings in the two standards 1. dium of eccentrics .7, 7, and couplings 8, 8, is adapted to reciprocate the vertically movable hammer 9, which is guided in its movement by the ribs 10, 100f the standards 1.

The plates 41 are held to the drum by means of the end flanges 11 and the drum is located directly beneath the reciprocable hammer, so that work may be supported directly above the selected pattern on the drum, and beneath and in the path of movehen held in this position, the work is ready to receive the stamped or printed impression as the machine is operated.

The work feeding device comprises a carrier plate 12 and spring clamping plate 13,

of which thesprings 14c urge the upper plate 12 into close contact with the lower plate. The work is to be carried between these two plates to and from operative position. A

,markers of the .pattern plates 4, as seen in Fig. 2. The carrier plate 12 is provided with side arms 17 17 which are supported between the standards 1, 1, in grooves formed by the parallel longitudinal ribs 18. At .the rear the side arms are connected This shaft, through the me- .70 with a plurality of faces 3 for the attachby the frame member 19. From this description it will be understood that the work carriage, as a whole, is adapted for reciprocation to and from working position, the whole being guided in the grooves formed by ribs 18. The reciprocation of the carriage is accomplished by the actuating sleeve 20 on the driving shaft 6. This sleeve is formed with the continuous cam groove 21 in which travels the roller 22 journaled on the arm 23. The arm 23 is secured to and rotatable with the pintle 24 which is journaled in ears 25 of the bracket 26. At the lower end of the bracket and secured to the pintle 24 is a second arm 27, formed with an elongated slot 28 at its free or outer end. This slot forms connection with the pin 29 protruding, from the fixed bracket 30 attached at the rear of the carriage frame 19. As the shaft 6 rotates cam sleeve 20 causes the arm 23 to swing on pintle 24 as its center. The movement of arm 23 is transmitted through the pintle to arm 27 which also swings on the pintle 'asa center. By means of the pin and slot connection of arm 27 and frame 19, the frame is caused to reciprocate, as will be understood, being guided between the pairs of ribs 18.

In connection with the feed carriage and work clamp we employ the inked ribbon 31, which is an endless band passing over the two rollers 32 and 33, and through slots 34 in the standards 1. Preferably the roller 32 is made of felt or other similar material, which may be moistened for the purpose of insuring a proper working condition of the inked ribbon as said ribbon passes over the .roller.v The roller 32 is preferably supported upon brackets 35 by means of the trunnions 36, the springs 37 pressing outwardly against the trunnions, and tending to take up any slack in the ribbon. This flexible support of the roller 32 also permits the hammer, as it descends, to depress the upper portion of the ribbon, as will be described. A step by step movement is imparted to the ribbon by a connection from the grooved cam sleeve 38 on shaft 6 which comprises the cam arm 39 and roller 40. A pawl 41 pivoted on the arm 39 engages teeth of the rack wheel 42 on the roller 33, and as the arm 39 is rocked by movement of the roller 40 in the cam groove of the sleeve 38, the engagement of the pawl with the ratchet rotates the roller 33 thereby moving the ribbon. A hand crank 43 may be provided on the roller 33, for moving the ribbon, for purposes of cleaning, etc.

In operation, assuming the carriage and clamp plate to be in position shown in Fig. 4, the work (two complementarily shaped pieces of leather for instance) is placed upon the carrier plate 12 and the clamp plate 13 is permitted to fall upon the work,

thus holding it firmly. The movement of the shaft, as described, causes the carrier to move rearwardly until the slotted plates 12 and 13 and the held work are directly over the pattern plate and marking pins. The hammer now descends and bears down upon the ribbon, as shown in Fig. 7, the springs 37 permitting the ribbon, and especially the upper portion thereof, to be depressed. In this manner the carrier plate, the clamping plate and the contained work are pressed between the upper and lower portions of the ribbon, and the pressure of the hammer causes the pins 5 to protrude through the slot 15 sufficiently to cause the impression of the pins and inked ribbon, not only upon the lower piece of work, but also upon the upper piece. In this manner the lower piece of work has the pattern imprinted or stamped upon its under side and the upper piece of work is stamped or printed on its upper side, at the same operation, thus providing a pair of flies for a pair of shoes. The continued movement of the cam 20 moves the carrier toward the front of the machine and the completed work is removed from the carrier and replaced by new material.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is 1. The combination with a reciprocable hammer in a machine as described, of an endless ribbon and supports therefor com-.

tern plate and a reciprocable hammer, of a work carrier comprising a slotted plate, a slotted clamp plate thereon, and means for moving said carrier to and from position between the pattern plate and the reciprocable hammer.

3. The combination with a supported pattern and a reciprocable hammer, of a slotted reciprocable carrier plate a slotted clamp plate connected thereto, an impression ribbon, rollers supporting said ribbon, and one of said rollers having a yielding bearing, for the purpose specified.

4. The combination with a supported pattern plate and a reciprocable hammer, of a work carrier comprising a slotted plate, a slotted plate spring pressed and hinged thereon, and means for moving said carrier to and from position between the pattern plate and the reciprocable hammer.
